What is the BMW steering gear matching method?

BMW steering gear matching method: 1. Enter the 44 power steering system; 2. Enter access authorization and input 40168; 3. After exiting, enter matching and go to group 60; 4. Place the steering wheel in the center position and press confirm. Then, manually adjust the toe-in based on the actual test drive to prevent deviation. The toe-in adjustment is made at the transverse rod of the steering gear and can be adjusted using a wrench. BMW is a German automobile brand under the BMW Group, which includes the i, X, Z, and pure number 4 model series, as well as the 1, 2, 3, etc. series, and the M series (BMW's official high-performance modification division) based on improvements to these series.
I've handled BMW steering gear matching quite a few times, usually requiring BMW-specific diagnostic tools like ISTA or INPA connected to the OBD port. First, ensure the vehicle battery is fully charged, the engine is off but the ignition is powered on, then run the software program, select the steering system matching option, let it automatically identify new component parameters for initialization and calibration. Never interrupt the power during the process, otherwise issues may arise, such as heavy steering or warning lights. If the matching is successful, it's best to test by turning the steering wheel to confirm proper return-to-center. For older models, sometimes a reset of learning values or sensor checks are needed. Remember, this job is a bit delicate, so it's safer for beginners to go to a professional shop to save money and hassle. Don't overlook regular maintenance; proper steering gear matching can improve driving precision and extend lifespan.
